(1) The default inputs to the modules are from the dedicated input terminals. The application must configure the PINMUX registers as shown in order to select the multiplexed input path, if
required.
(2) The SPI4CLK, SPI4SIMO, SPI4SOMI, SPI4nENA and SPI4nCS[0] signals do not have a dedicated signal pad on this device. Therefore, the input multiplexors on these inputs are not
required. The control registers are still available to maintain compatibility to the emulation device.
(3) When the muxed input is selected for GIOB[2], the PINMUX9[16] and PINMUX9[17] must be cleared. These bits affect the control over the PULDIS (pull disable) and PSEL (pull select).
When the multiplexed input path is selected for GIOB[2], the PULDIS is tied to 0 (pull is enabled, cannot be disabled) and the PULSEL is tied to 1 (pull up selected, not programmable).
